Building zinc fingers by selection: toward a therapeutic application.

Abstract excerpt

A phage display approach was utilized to modify the specificity of each of the three fingers of the murine transcription factor Zif268. Selections were performed by using the consensus binding sequence of the natural protein and a conserved sequence in the genome of the type 1 human immunodeficiency virus. By using an extensive randomization strategy, the entire 3-bp specificity of a finger has been changed....
